What are my options for sprints this week?

Sprints are short intervals of running or walking. If you are able to run, you can do incline sprints by running uphill for 20- 30 seconds, and then slowing down for 30 seconds. Once fatigue sets in, you can move to 30 seconds sprints and then 1 minute recovery. If you are only able to walk, you can do this similarly with increased incline walking as fast as you can for 1 minute and then recover for 1 minute. Again, when fatigue is present, walk fast for 1 minute and recover for 2 minutes.
